LAUNCHXL-F28069M: UART jumpers

Part Number: LAUNCHXL-F28069M


Hi,

I'm trying to send and receive serial data over SCI_A using LAUNCHXL-F28069M. In page 7 of the LAUNCHXL-F28069M Overview User Guide, there is a table describing how to setup the jumpers for serial communication. I plan to use a usb-to-serial converter on my laptop to send and receive data. Should I setup the jumpers in ON-ON position to be able to send and receive? 

Thanks,

    Kash,

    With that setting the LaunchPad USB to UART adapter will be disabled and information will not be sent back to the host PC. For more details on the jumper settings, please see the schematic on page 16. On that page you will find a table with the channel descriptions.

    I hope this helps. If this answers your question, please click the green "Verified Answer" button. Thanks.

    Right, but I should be able to see the messages on my laptop as long as I have my usb-to-serial converter connected to J1.3 and J1.4. Right?

    Kash,

    That may work, but you might need a transceiver. Remember not to exceed the maximum voltage rating of 3.3 V for the GPIO. We cannot give you an exact answer since we do not know anything about your USB-to-serial converter. Again, be careful not to exceed maximum ratings for the device.
